hey, about the cloak, it's really easy. you get a cape, put it on a minifig, take the arms off, and try to get the sides of the cape even on both sides of the minifig. try to put the arms on over the cape (they wont fit in) then, you'll see the marks left on the cape by the arms, get a pair of scissors, poke a hole in the marks, put it back on the minifig, and put the arms in. it kinda automatically makes a collar, too.
peace out, dylan.
